As they stood outside trying to figure out how to arrange themselves,the '00 line plus Jeongin were fooling around,letting the elders choose the seats.
Hyunjin and Jeongin were in their own world as JaeSung climbed onto Felix's back and Jisung climbed on Seungmin's back.
"Yah,Han is too heavy!"Shouted Seungmin,trying to adjust Jisung on his back as the former made an offended face.
"Bok,switch with me."Seungmin begged and Felix shook his head,holding onto JaeSung tightly.
"Nope,she's mine."He said and JaeSung laughed,placing her chin on top of Felix's head and sticking her tongue out at Seungmin.
Seungmin placed Jisung on the floor and the two only glared at each other.Jisung playfully pushed Seungmin who retaliated and poked his stomach harshly causing Jisung to stick his hands up in surrender.
"Alright kids,let's go!"Chan shouted before pointing at them,"And you two,calm down.Felix but Jay down."Felix whined but let the girl down.
They followed into the restaurant and were lead to a circular table in one of the private rooms of the restaurant.
"So we didn't end up choosing seats so seat where you would like,I guess?"Chan said and the rest nodded.In an unspoken agreement,JaeSung,Seungmin,Felix and Jisung sat together and coincidentally Jungkook and Namjoon sat with them.
"What is this?The September line?"Hyunjin asked,and Namjoon and Jungkook looked at the three from September in surprise.
"What day were you born?"Jungkook asked Seungmin who proudly said the 23rd causing Jungkook to snicker before looking at Jisung and Felix.
"Ours is interesting."Jisung said."How many days do you think are between us?"Felix slightly smiled as he took a sip of water causing Jungkook to look at him suspiciously.
"Five days?"
"Nope."Felix said looking at his senior with a giddy smile."It's less then that."
Jungkook thought about before tilting his head as the rest quietly watched."Two days?"
Jisung shook his head and Jungkook's eyes widened.His jaw slightly dropped before answering.
"One day?"He asked as if he wasn't sure but with a nod from both he gasped loudly.
"One day?Seriously?!"Jungkook asked excitedly and they nodded again."Wah that's crazy,that's cool.Who's older?"
Jisung puffed out his chest causing the rest of the table to laugh.He flicked his hair and turned to Jungkook with a big grin.
"Me of course."He said and Felix shook his head.It seems that during their conversation,the older members had orders as the food arrived.
"Do you use it against him?"Jungkook asked and Felix groaned,setting his chopsticks down.
"Everytime."Felix complained and Jungkook couldn't help but find it adorable."When he asks me to get things for him and I say no he's like 'I'm older than you'."He said,mimicking Jisung's voice.
The table erupted into laughter as Jisung flushed red,not expecting Felix to call him our.
"He's annoying but when he's quiet you miss him."Hyunjin said causing Stray Kids to cringe,but their seniors only smiled,knowing that soon they won't want to leave each other.
They soon became quiet as they ate,only speaking when they wanted something passed.At the end of the meal,Jeongin offhandedly said he had to unbutton his pants causing the rest to shamelessly say they did too which lead to giggles erupting from them.
"Can you guys squeeze in dessert?"Jin asked,and Stray Kids sat up nodding their heads.
The older group looked at the younger ones before Jimin sheepishly mentioned that he really wanted ice cream.Jungkook nodded,waving over the waiter.
They ended up ordering ice cream and to the delight of Jisung,cheesecake.The smile on Jisung's face made a brotherly smile erupt on BTS's face as the younger group enjoyed their desserts.
JaeSung was sharing with Seungmin as she wasn't sure if she would finish the ice cream herself,and Seungmin offered to share his.
"Seeing you guys eat makes me happy for some reason."Taehyung said causing the group to feel slightly embarrassed.Taehyung lightly ruffled Changbin's hair causing the rapper to flush red.
"I'm adopting you guys."Yoongi offhandedly said,shoving a spoonful of ice cream immediately after.
"Hey,you're officially my kids."Jimin said,completely and utterly serious."You can come to us or if you need advice or just want to talk we'll be here."
Admiration and respect basically flowed off of Stray kids as Jeongin cutely clapped his hands.
"Wait,"Minho said,"If we get asked a question about you,can we say Hyungs?Or do you want us to call you sunbaes?"
"Hyungs."Jungkook said immediately,"We already established our brotherhood through this meal."He said and everyone nodded."Plus you guys already have our numbers don't you?"
"I have Namjoon hyungs."Changbin said and Namjoon nodded.Jungkook grabbed JaeSung's phone and the girl slightly protested before realizing what he was going to do.
"What groupchat has 20+ members?"Jungkook asked and JaeSung took her phone back.
"You have the '97 line groupchat,we have the '00 line group chat."JaeSung said,making a groupchat with BTS and Stray Kids.
"Ah,BamBam talks about the '97 groupchat alot."Chan said and Jungkook looked at Chan,momentarily forgetting that they were born in the same year.
"What month were you born in?"Jungkook asked curiously.
"I was born in October,Woojin was born in April."Chan said and Jungkook giggled looking at Woojin.
"That makes you my hyung."Jungkook said giddly and Woojin chuckled lightly and nodded.
"Here,I'll add you to the groupchat."Jungkook said,holding his phone out to Chan and Woojin."I can't believe BamBam hasn't added you to the group chat."He grabbed his phone again and added them in.
Namjoon got up and slightly stretched before adjusting his glasses.
"Alright,we have a meeting in a few minutes so we'll pay and go first of you don't mind."
Chan stood up,"It's fine,we have to head to practice anyway."
Goodbyes were said and hugs were given out before both groups separated.
The two groups walked to their designated vans and smiled to themselves,knowing new forever last friendship was created.
